Absolutely! My hubby has a friend who carries a great deal of negative engergy around with him. I don't think he's a bad person, just really messed up right now. My laid back lazy Preacher hates him. One night, I hadn't heard anyone drive up, but Preacher went insane outside. He was on his "you must have to pee" chain. (Preacher hates to go outside so we have a tie-up right outside the door for him) I went to see what all the racket was about and Preacher had Darren pinned against the wall--hackles up, teeth bared, going to rip him to shreds if he moved. It took me quite awhile to get Preacher to back off. Even now, Darren honks his horn and we get Preacher out of his way. Preacher also becomes very protective if I am home alone and someone comes over.

I also believe that my dogs know things when we are out on the sled. I never force them to cross ice or go down a trail. I believe that if my lead dogs absolutely refuse to go somewhere, there's a reason!
